Sub: DESIGN OF PORTABLE EQUIPMENT FOR
TRANSPORTATION BYOILFIELD TRUCK
& TRACTOR TRAILER UNIT
Transport Department often faces difficulties in loading/off-loading and transportation of equipment which do not conform to the general dimensions or design required for safer and quicker transportation by our oilfield trucks and tractor trailer unit. Therefore, for convenient handling and transportation we request the departments concerned to consider the following points while new equipment are being designed/procured or new skids are being fabricated.
1.0Overall dimensions of the equipment should preferably not to exceed 9m x 2.5m x 2.75m (Length x Breadth x Height). The corresponding dimensions for the self-loading type of skid should be 9m x 2.5m (L x W).
2.0The overall weight of the equipment to be transferred by tractor trailer unit should not exceed 18 MT and for Oilfield Truck28 MT.
3.0For a skid of 2.5m width, there should be at least four longitudinal main sections, preferably each one of single length and should have a smooth finish underneath and curve finish at both the end, so that the skid can roll over the loading roller and body of the truck without any obstruction.
4.0The skid so designed should be sufficiently strong and properly welded at joints and should be able to withstand any shocks which are bound to come while being handled and transported over rough and slushy roads/locations. Height of the joint used for the longitudinal members should be minimum 20 cm.
5.0As far as possible the length of the skid should be at least 1(one) meter longer than the overall length of the equipment mounted on it, and also equally distributed on either ends. On no account should the skids be less than 3(three) meters in length, irrespective of the length of the equipment that is to be mounted. The C.G of the load should preferably be located at the middle of the equipment.
6.0As far as possible the roof and the side walls of the portable equipment/tools hut/godown/ office etc. should be fabricated from M.S. plates and welded instead of using joint bolts which work loose due to vibrations. Roof ends and corners should be rounded off so that these do not pull the telephone/guard lines, should these come in contact with them during transportation. The use of C.I. sheets should be completely avoided.
7.0To withstand vibrations and jerks, suitable supports should be provided on the vertical posts and below extended fittings/pipe connections of the equipment which are skid mounted.
8.0We shall appreciate if the department concerned associates with the Chief Engineer (Fields) or Head-Transport for any clarification that may be necessary at the time of designing/procuring new equipment.
9.0This supersedes our earlier circular on the subject please.
